There are many books "http://www.reddit.com/r/AskHistorians/wiki/books" suggested but obviously some user more erudite than me could give to you some other tiltle that aren't listed. Also try to search " Vikings" and "greece" and themes related in this subreddit and try to find youself some other book that aren't in that list linked above. Sorry for the weak reply. Have fun.
